In general, any vehicle over 11 feet in width, 13 feet 6 inches in height, and within the super heavy weight class (over 150,137 lbs) should obtain an oversize load permit from the IADOT and potentially additional permits from LEMDOT.

To navigate the complexities of Le Mars's infrastructure, it's crucial to plan routes that avoid sensitive areas like Le Mars Convention Center and major construction zones along the Le Mars College Campus area.
